ooiazenm'rron-roox AND GIRCUIT-BREAKER.

To all whom it may concern p Be it known that I, GEORGE BUCKEYE, a citizen of, the United States, residing at Kansas City, in the-county of Jackson and State. of'.Missouri-, have invented. icertain new and'usefullmprovements in Combina- -tion-Locks and Circuit-Breakers, of which All the following is a specification.

My invention relates to improvements in combination locks and'circuit breakers, and

111 primary object is to provide a device w' ereby,unauthorized--persons may be prevented from closing the circuits of automobiles and thus running-the same.

In order that the invention may befully understood, reference will now be made to the'aecompanyi'ng drawing in which:

1 is a front elevation of the device. Fig. 2 is a rear'elevation of the device with aback-plate forming a part thereof removed "to show the interior mechanism. Fi 3 is a horizontal section taken. online 11 III ,of. Fig. 2. Fig. 4 showsa group of tumblers employed in carrying out the "invention:

Fig. 5., is a vertical section taken on line V--V of Fig. 2, andFig. 6 shows a diagram of a circuit, such as is commonly employed on a gasolene driven car. 7 I

In carrying-out the invention, I employ a cylindrical casing- 1, preferably, struck from a piece of sheet metal and provided with .a. removable back-plate 2, upon which the interior mechanism of the device' is assembled; Aiter such assembling the backlate is firmlysecuredin place by'placing it against an annular shoulder 3' of the casing and crimping the'margin of the same over said. back-plate, as shown, in Figs. 3

and 5. Back-plate 2 is provided with. a pair.

distud-bolts. 4 adapted to extend through Ttl e dash-board of an automobile (not shov n). and, be secured thereto by a pair of nuts" 5.

,6 designates a knob which is journaled in the front. side of the casing and provided with adial'Lcoacti g with an O on the face of the casin' so that the roper combinationfor controlling the c rcuitbreaker may be readily found by a person Specificdtion of Letters Batent.

duced threaded portion entering a corre- 'spondingly-threadedcounterbore in the knob to firmly draw the inner end of the same against a tumbler l0, and bind said. tumbler ,against a sleeve 11, embracing the screw and abutting against the head-thereof.- so that the knob, the screw, the tumbler 10, and said sleeve will rotate together when the knob is turned. Tumbler 10 has a projecting stud. 12.

13 des 1gnates a second tumble'iy which is loosely-mounted upon the sle'eve 11, and proaIid 15, the'zformer of which coact with stud 12. p 16 designates a third tumbler, which like tumbler .13 is loosely-mounted upon the laterally- :vided with oppositely-projecting studs 14 is adapted to sleeve 11-, said third tumbler being provided A with a laterally-projecting stud 17 adapted to coact with stud 15 on tumbler 13.

Tumblers 13 and 16' .have peripheral notches 18 and19, respectively, td receive internal" teeth .on a movable circuit-breaker member 21. Tumbler 10 has a lowradius 22 on a level with the bottom of notches 18 .and 19, and a high-radius 23 on a level with the peripheries ofJtumblerS-B and 16, for the purpose of controlling the movable member 21 of the circuit-breaker, as will hereinafter appear. a

Tumblers 10 and 16 are spaced equal distancesfrom tumbler13, by two washers 24.

mounted upon sleeve 11. and provided with.

internal lugs 25, which enter a peripheral groove 26 in the sleeve, so that the washers i will turn therewith. I

The movable member 21 of the circuit? I breaker comprises three yoke-shaped arms 27 barrying theteeth 20, an arcuate fiber member '28 connected to the 'endsof arms 27 by pins 29, and a rotary terminal 30 mounted in a longitudinal slot-31,in the face. of member 28. The yoke-shaped "arms. 27 are pivotallymounted upon a pin 32, secured to the back-plate 2, and the two outer arms are spaced equal distances fro-m1 the inter-. mediate-arm by a pair of washers 33.

The rotary terminal. 30 of the circuitbreaker coacts with a resilient terminal. 34

fixed to 'a pieceof fiber 35, secured in the casing and havinga slot. 36 in which said terminal 34 is located. Slot. 31 permits member 28 to move vertically without "contactihg withterminal 34', and slot 36 permits terminal 30 to move vertically without manner.

In Fig. 2, of the drawing, the circuitbreaker is shown closed. To open the circuit breaker 'and thus interrupt the circuit, it is only necessary to rotate tumbler 10 until its high radius 23 passes beneath teeth 20 and thus raises the movable member 21 until its terminal 30 is out of contact with terminal 34. This operation also raises the teeth 20 to a level with the peripheries of tumblers 13 and 16, so that further turning of tumbler 10 will cause the rotation of tumblers 13 and 16, through the intermediary of studs 12, 14, 15' and 17 until notches 18 and 19 pass out of register with the teeth 20. It will then be impossible to again close the circuit-breaker and complete the circuit until the tumblers are properly manipulated to bring the low radius 22 and the notches 18 and 19 in register with the teeth 20, which can be readily done by any one familiar with the combination. When desired, the combination can be readily changed by loosening screw 9 and turning tumbler 10 to a difierent point upon said screw.

While the device has been shown and described for use in controlling the circuit of an automobile, I of course, do not limit myself to this use, but reserve the right to employ the device wherever it may be used to advantage.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

1. In combination, a device consisting of a casing, a knob journaled in said casing, tumblers within the casing 'controlle by said knob, and a circuit-breaker contro led. by

'said tumblers, said circuit-breaker embodysaid knob, and a circuit-breaker controlled by said tumblers, comprisinga plurality of yoke-shaped arms pivotally-mounted in the casing, a slotted arcuate member connected to the terminals of said arms, a terminal mounted in the slotted portion of said arcuate member, and a resilient terminal adapted to coact with the first-mentioned termie.

nal. I

3. In combination, a device consisting of a casing having an O on the facethereof,

a knob mounted in said casing and provided,

with a dial adapted-to coact with the O on the face of the casing, tumblers within the casing controlled by said knob, a plurality of said tumblers having peripheral notches, and the remaining tumbler having a low radius ona levelwith the bottom'of said notches, and a high radius on a level with the peripheries of the first-mentioned tumblers, and a circuit-breaker comprising a plurality of yoke-shaped arms pivota1lymounted in the casing and having internal teeth to coact with the tumblers, an arcuate fiber member connecting the ends of said:

yoke'shaped arms, a rotary erminal mount-""5 ed on said arcuate fiber member, and a resilient terminal adapted to coact with said rotary terminal.

In testimony whereof I aflix my signature, .in the presence of two witnesses.

GEORGE J. BUCKEYE.
